- Some of the established flow battery players have opened impressive automated production lines, rapidly bringing down the cost of flow battery stacks - the most cost-intensive hardware component of a flow battery system.
- Some really large flow battery installations are in progress - most notably a 1.6 GWH / 800 MW installation in Switzerland by FlexBase Group to be co-located with a data center where the flow battery will be placed in three layers in the basement. A great example where the non-flammability of flow batteries led to the choice of the technology.
- Rongke Power presented an impressive 3.4 GWh (or 3.2?) of active vanadium flow battery assets under their management, almost half of the globally installed capacity.
- Large-scale battery installations proceed extremely rapidly. The time for the procurement procress and installation can sometimes take less than a year, and installation less than 6 months.
- In California, the largest LIB installation was just confirmed, 4.6 GWh at a cost of about 5 billion USD - seemingly a bit more expensive than the 350 usd/kWh that is often quoted. Still, Californa - perhaps due to their brave investments in renewables - have climbed from being the worlds 10th largest economy 2012 to reaching 4th place in 2025.
- LDES is growing but is still in its early stages, and is expected to see an explosive growth in the years 2035-2050 (valued at US$223B in 2044)
- The Vanadium electrolyte price is at one of its historically lowest points, and is expected to increase, but uncertainty about how much. However, projections seem to point towards the supply being able (albeit just barely) to cover the future increased demand.
- Personal reflection: The flow battery society has shifted towards a more collaborative mindset. The field is joining hands to share experiences on topics not directly related to the technology such as market information, business models, supply chain management, project management, standards and perhaps most importantly, policy.
Thanks IFBF and Flow Batteries Europe for a great conference!
